RFC draft for segment routing over UDP/QUIC

This document defines the Segment Routing Header(RFC8754) extension in QUIC transport protocol. It will provide a new general purpose transportation layer with the following features:

• Secure [QUIC TLS]
• Reliable [QUIC Transport]
• Programmable [Segment Routing]

There is easy for understanding presentation available in:

We just did some hack on quic-go to provide userspace quic support.

//quic-go create session session, err := quic.DialAddr(*remoteSock, tlsConf, config)

//update QUIC-SR segmentlist and it could be runtime modified. session.SetQUICSR([]string{1.1.1.1:2345,2.2.2.2:4567}, []byte{0x1, 0x2, 0x3})
